Sun Cluster HA for Sun Grid Engine as released with Sun Java Enterprise System 5 enables multiple sge_qmaster instances to run in a Sun Cluster configuration. To enable multiple sge_qmaster instances to run in a Sun Cluster configuration, you must specify the port number
for each sge_qmaster instance explicitly. The sge_register script sets required Sun Cluster resource properties on the basis of the setting of MASTERPORT.

You cannot use the file /etc/inet/services to specify the port number for the sge_qmaster daemon. This file enables the port number to be specified for only one sge_qmaster instance.
